Teenage Mutant Milk-caused Hurdles
Much Apu About Something

Teenage Mutant Milk-caused Hurdles is the eleventh episode of Season 27.


A new teacher named Carol Berrera (guest voice Sofia Vergara) arrives at Springfield Elementary, and a smitten Bart attempts to win her over.

Meanwhile, Homer decides to buy a new brand of “milk,” which causes early puberty, both for Bart (augmenting his wooing powers) and Lisa (whose small bout with acne opens her up to the world of makeup and popularity).[5]

Full Story

Groundskeeper Willie was trying to be a substitute teacher for the forth grade, but in order to make the kids quiet, he starts playing a bagpipe. Superintendent Chalmers enters the room and tells Willie to stop playing the instrument and leave the room because there was a new teacher: Mrs. Berrera.

Bart started acting weird when she first entered the room, and later realized that he has a crush on her new teacher. Meanwhile, Homer has to buy a healthy milk for the family, but Apu makes him buy a cheaper milk full of hormones made by Buzz Cola.

The next morning, the family discovers that Bart was the first to wake up and was already dressed for class. Lisa mocks Bart that he's only doing that for his new teacher, which is true.

Homer drives Bart to school only to see her, and they're surprised by other dads, also eavesdropping on her class. Later, Bart writes "Skinner is a wiener" on the school's wall, but it's surprised by Mrs. Berrera saying that she needs to see him after class.

At their meeting, she tells Bart that he's way behind the class and need a tutor. When Skinner offers help on her class by pulling up her maps, Bart discovers that Skinner is also trying to impress Mrs. Berrera.

The next morning, the milk hormones started making effect on Bart (who now has a little mustache), Lisa (who now has an acne problem) and Maggie. Marge decides to help Lisa while Homer teaches Bart to shave his beard, where he discovers that he has to take the plastic cover off the blade for it to work properly.

Meanwhile, Lisa tries to hide her face with a hoodie, but Marge changes her mind by presenting her to makeup in order to hide her skin problems.

At school, Bart pretends he's hurt to draw Mrs. Berrera's attention and take her away from Skinner to help him with first-aid. At the watching crowd, Nelson discovers that Lisa is using makeup, which makes her popular enough to be invited to a third grade party.

The next day, at breakfast, Marge discovers that the Buzz Milk is the one causing problems to the kids. They call the number on the box, but Snake picks up the phone in prison.

Later at school, Bart sees Mrs. Berrera and Skinner kissing on the corridor. He also calls Bart for a meeting, saying that he knows way more things about Mrs. Berrera than Bart does, and that he doesn't have a chance to win her.

Angry by Skinner's play, he decides to prank them by filling a chocolate box given to Mrs. Berrera by Skinner with class pets, such as snakes and frogs.

Later, at the third grade party, Lisa realizes that it's about to rain and everyone would see her acne problem if the makeup washes away, resulting on humiliation, but she decides to reveal her problem herself by taking off the makeup in front of everybody, but her skin is clean and she notices that the hormone effects are gone, so she decides to leave the party, embarrassed for making an underwhelming announcement.

Lisa convinces Bart to give up on Mrs. Berrera and let Skinner have her as a girlfriend, but when he presents her to Agnes, she gets so disgusted about his mother that she decides to end her relationship with him.

At night, Skinner, Bart and Milhouse decided to roast marshmallows at the school, using Bart's permanent record as fuel to the fire, while Lisa plays her saxophone in the music class.

At the next morning's breakfast, Lisa's playing saxophone at the kitchen, claiming that she'll never use makeup again, but Bart mocks her by saying "Carnegie Hall" out loud (which according to her, it would make her dream of playing there not come true).

They start fighting on the floor, but they're separated by Maggie, who now has a huge mono-brow and super strength due to the milk hormones.
